Interesting, this "hung" Parliament result looks alot like what happened in germany...
and USA in Gore v Bush ... was America the trendsetter here?
New Zealand had a fairly similar result in 1993 - National 49, Labout 46, NZF2, Alliance 2.
National and NZF formed a coalition of 51-48, with a member of Labour being voted in as Speaker to make it 51-47 This was the first coalition required in decades.
Since then New Zealand has changed to a German-style MMP system where the makeup of PArliament is based on the % of party vote rather than winning electorates. This makes it much earier for fringe groups (like to Greens) to get in - since MMP came in in 1996 there has not been a single-party victory.
In a sense the United States is a trend setter in the sense that it is actually an even divide between an ideologically vigorous Left and a ideologically likewise vigorous Right. You see this in New Zealand - where if you take New Zealand First and United Future as the "Right" it is almost a 50-50 divide for the country. Dear Helen could be referred to as a "balated" catch up version of Clinton.
It does not relate to coalition government - in the case of New Zealand 1996 the parties that constitute the "Right" today is well over 50% of votes, while in 1993 the Left would have handily won in proportions had it not been the first past the post (winners take all) system. Germany's case this time is more complicated - the Left dominates, but you can see the Right is not much weaker there.
